LIFE-sAvING swmirmq BELT 'i Application led August 28, 1928. Serial No. 302,50).r

This invention relates generally to life preservers, and has more particular reference to J a novel life preservcr adapted for self-infiation. i `5 The' invention uhas for an -object the provision of a device of the class mentioned -which is of simple durable construction, desirable and eiicient'in action, and which can be manufactured -and sold at a reasonable cost.

The invention proposes the use of a cartridgecontaining a highly compressed gas such as carbon dioxide (CO2) and having puncturable end. This cartridge is sup- 15 ported ina bracket arranged for clamping it againsta rubber gasket held in a stem -member connected with pipes which. in turn connect with inflation members arranged for being secured about the body of a' wearer. A means is provided for puncturing the sai-d end of the cartridge for releasing the compressed gas and allowing same to enter the.,

the stem member 21 has a'reduced portion 26 inflation member.

For further comprehension of the invention, and of the object and advantages thereof, reference will be had to the following description and accompanying drawings, and

' t0 the appended claims inwhich the various novel features of the invention are more particularly set forth.

In the accompanying drawing, forming a material part of this disclosure".-

Fig. 2 is aside elevational viewf the de [may be loosened from stem.21 so that the l. escapes out of the cartridge and iows thru The reference numerall() indicates genery ally the user, and the iniation members 11 are shown engaged about his body. The wearer has a belt 12 which is used inholding the compressed gas portion 13 of the device. `55V The inflation members llmay beef any design or construction and have straps such .as

15 for attaching to a wearers body.

The compressed gas portion 13 of the device consists of a bracket 16 centrally ar-l 60 ranged with a recess 17 for holding a gas containing cartridge 18, and the rear of the bracket isprovided with aboss 19 formed with a niche 2() for receiving the rear of the cartridge 18, and thc front portion of the'65 bracket has an internally threaded llange 20.

A stem member 21 is shown engaged within the flange ,20 and is provided with a recess 22 holding a tubular-gasket 23`by reason of a lock collar 28 threadedly engaged therein. 70 This collar isffor'med withcuts 25 for engagement by a turning tool. The front of handle is da puncture member 31 ponsisting preferably of a solid needle.

v In operation of the device the bracket-16` cartridgeV 18 may be slipped out of thek bracket,'or the bracket 16 maybe tightened upon the stem member 21 for forcing thecafrp tridge against the-tubular gasketl 23 which is preferably of rubber.' Inthe event that the user of the device is-inf'distress, he may move the handle 28l for moving the needle 31 rearwards and puncturing the front end oi the cartridge'18.- The compressed gas then the tube 27 into the inflation -members 11. It is ,eadily seen that this will support the wearen against drowning The bracket 16 is provided with side lugs life preservers, but also for inilating rubber.

cartridge is shown. reduced at 18 'and has an opened end n'ormally sealed by a puncturable member 34.

In the modified form of the device disclosed in Figs. 7 and 8, the cartridge 18 is shown formed with a plurality of concentric cuts and a serrated member 36 is shownv pivotally mounted on the lugs 33 and movable against the cuts 35 as shown in full lines in Fig. '8. The dotted' lines show the serrated member disengaged from the cuts 35.

After the bracket 16 has been tightly turned for moving the cartridge against the tubular gasket 23 it will be found to be very tightly engaged in this part. The serrated members 36 maysbe held against the cuts 35, While the bracket 16 is turned loose, and this simultaneously draws the cartridge 16 rearwards disengaging. same from the tubular gasket 23.

It is to be understood that my device may be used not only in connection with garment boats, belts andthe like. L

While I have shown and described the preferred embodiment of my invention, it is to bel 'understood that I do not limit myself to the precise construction herein disclosed and the said recess, an vinternally threaded flange formed at. the front end of the bracket, a-

right is reserved to all changes and modications lcomin Within the scope ot the invention and as dened in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters'Patent is `1. In a device of the class described, a

bracket formed with a recess for receiving a j cartridge, a boss with a niche formedv at one v:end ofthe bracket for forming an abutment for the rear of a cartridge engaged in the stem member engaged therein, a tubular lgasket secured Within the stem member and' arranged for receiving the -front'.reduced porengaged in the said recess and having a punca' turable front end', a means for forcing the cartridge o-ut of engagement With the said gasket upon turning the bracket oft' of the stem, comprising a serrated member pivotally mounted` on said bracket and manually engageable with concentric hcuts formed on said ceivi-ng the front reduced portion of a cartridge Within the said recess, a tube for connection with inflatable member secured on the stem, a ompresse'd gas holding cartridge engaged in the said recess and having a punct-urable front. end, a means forv forcing the 4cartridge out of engagement with the said gasket uponturning the bracket oliil of the stem, comprising a member movably mounted on said bracket andmanually engageable with concentric cuts formedV onsaid cartridge, and

means for puncturing the said end of the cartridge When desired. 1 l

In testimony whereof I have aiixed my signature.
